Overview
The AD830AN, produced by Analog Devices Inc., is a wideband, differencing amplifier designed for use at video frequencies and other high-speed applications. This amplifier accurately amplifies fully differential signals while rejecting common-mode signals, even at high frequencies. It is particularly useful in applications requiring high impedance inputs, excellent common-mode rejection, and fast dynamic performance.
